What is the deal with Zeff?

[amc32]

what is the deal with these ubuy Zeff "clarion" amplifiers. I have had absolutely no luck repairing them. The power supply appears to atyipical but the boards also seem to be 3-layered and untraceable. I've had to walk quite a few of them because I don't need the dead weight.One look at the torroids used in the power supplies will remind you Coustic's 460's and 960's very sloppy. Any tech advice on Class G/H would help out alot also.

Please let me know if I'm the only person that dislikes repairing these amps.

The amplifier circuits are, in many ways, identical to the older Zapco amps. The service manuals are readily available for many of them. I hate working on them but that's because of the way the case is put together. Too many screws and panels to deal with.

What model amp are you working on?
